A Global Positioning System (GPS) is a navigation system that is satellite-based and works in any weather condition, anywhere you are in the world, at all times. It’s a system of at least 24 GPS satellites that were made available for civilian use in 1980, and they allow this marvel to happen. It’s fantastic if you’re out of cellphone range because it works everywhere. These GPS navigation systems allow you to safely and easily navigate without needing a cellphone signal or draining your phone’s battery.
